EMIL G. GEBAUER, OF CHICAGO, ILLINOIS.

CAR-SEAL.

To all whom it may concern:

Be it known that I, EMIL G. GEBAUER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Car-Seals, of which thefollowing is a specification.

My present invention relates to car seals, and more particularly to thattype of car seal described and claimed in my Patent #952,801, grantedMarch 22, 1910, my object being to improve my patented ear seal withrespect to simplicity and effectiveness in the prevent-ion of tamperingwithout detection.

With this in mind my invention resides in the features of constructionand arrangement, to be hereinafter described with reference to theaccompanying drawing, in which,

Figure 1 is a plan view of one side of the shackle removed. Fig. 2 is asimilar view looking at the opposite side of the shackle. Fig. 3 is aplan view of the complete seal closed and locked. Fig. 4 is an enlargedsection through the cap and the locked ends of the shackle, taken on theline fir-4: of Fig. 3, and Fig. 5 is a detail cross-section, taken online 55 of Fig. 4.

Referring now to these figures, the shackle 1, which is preferablyformed of a strip of sheet metal, is provided with an aperture 2 at oneend, and is slitted adjacent to its opposite end to form a tongue 3,which is struck outwardly therefrom for a purpose to be hereinafterdescribed. Immediately beyond the tongue 3,the shackle 1 has a reducedneck portion 4, and terminates beyond said neck 4 in a rounded head 5havthe side recesses 6. The said reduced neck portion 4 is formed, asshown, by turning up the side edges of the shackle at this point, theseside edges being cut away to form projections 7, constituting catches.The last mentioned end of the shackle is inclosed by a thimble or cap 8,the open and closed ends of which are pressed fiat, and the intermediateportion of which remains rounded about the catches 7. The closed end ofthis cap 8 also has portions 9 pressed inwardly within the side recesses6 of the shackle head 5 in order to securely lock said shackle in saidcap and prevent it from being thereafter withdrawn.

Specification of Letters Patent.

Serial No. 621,611.

The inner end of the thimble or cap 8 extends to the tongue 3, asparticularly shown in Fig. 4-, which tongue is bent to lap over one sideedge of said thimble, and thus prevent the projection of the oppositefree end of the shackle into the cap except upon that side from whichthe catches 7 extend. \Vhen it is desired to lock the shackle this freeend is projected within the cap 8 until its aperture 2 extends over thecatches 7 in looking engagement. Thus the locking engagement of theshackle ends is concealed by the cap 8 from manipulation with a view toreleasing the same. The formation of the tongue 3 weakens the shackle atthis point to such an extent that any continued tampering will result inits being broken at a point where it will be impossible to conceal thebreak, while the tongue itself prevents the free end of the shackle frombeing forced into the cap 8 upon the wrong side of the connected end,where it might be held in such a manner as to deceive the ordinaryobserver and still remain unlocked and permit of ready subsequentreleasing of the seal.

It will be understood that the shackle is to have stamped or otherwiseplaced thereon, an identifying number and the name of the road using theseal in order to prevent substitution,

I claim:

A seal lock comprising a strip one end of which has a recess, and itsother end having a head provided with recesses on opposite sides, and aneck joining said head to the strip, said neck being formed by bendingthe edges of the strip outwardly, said bent up edges being shaped toform catches which are adapted to enter the first-mentioned recess, anda cap inclosing the neck and head of the strip, said cap havingindentations which enter the recesses of the head, and the strip havinga tongue which fits over the edge of the cap .at one side of the mouththereof.

In testimony whereof I aflix my signature in presence of two Witnesses.
